The room schedule and rooms are associated; therefore, all fields that appear in the room schedule are part of the properties list for the room.
If you modify field values in the schedule, the corresponding property values update for the room, and vice versa. Also, this association extends to room tags. For example, if you change the room name in the schedule, the room and related tags update and display the new name.
Room tags are annotation elements that display values from the room properties. The properties of a room tag are the properties of the annotation family. If a room is selected in a schedule, you can click Show on the Modify Schedule/Quantities tab to see the position of the room in any related view.
